This application is a refiling 01' my application U. S. Serial N0. 189,558 filed May 7, 1927. y

This invention relates to a book mark 0f the kind l1aving a clasp adapted to slip over the top edge 0f the back 0f the binding 015 a book.

Hefetofore, such clasps have been proviclecl with ribb0ns 01 flexible cords adapted to bc drawn between the leaves of the book t0 ma1k the place. Such flexible place marking devices have the disadvantage that they were n0t readily discernible when in place between the leaves; d0 n0t facilitate the separation 01 the leaves at the desired place; become readily mussed and crumpled up and soilecl and contribute to the tearing 0'f the leaves when an attempt is made t0 0pen the book at ehe place marked thereby.

T he present invention has for its object tl1e rovision of a book mark which shall av0icl the disadvantages inhcrent in previously known book marks ancl which shall be applicable to books of substantially any size.

In accordance with the invention the clasp comprises a flap formecl with a downwarclly extending tongue cut out therefrom, the flap being adapted to be insertecl within the inside of the back binding 0f a book with the tongue outwardly 0f the binding so as to grip the binding therebetween. The clasp is also provided, above t-he tongue, with an elongatecl transversely extending slot. The slot preierably has an arcuate sicle npon whlch is carlied a place marking fingen 0x man. This lnger is prelerably so designed as 170 be capable 0f extencling laterally from the clasp 110 mach the lcaves atljacent the c0vers 0f thc book.

The invention also has t0 (10 With a book 1nark Which shall be practical from the standpoint 0f ease and cheapness 0f manufacture and convenience and durability in use.

These und other objects 0f the invention and the means f0r their attainment Will 110W be clescribecl 1n0re full v with 1eference t0 the accompanying drawings illustrating 0ne embodiment by which ehe invention 1nay be realized ancl in Whicl1:

Figure 1 is a view in elevation showing a fragmentary portion of a book with the book mark in place.

Figure 2 shows the book mark 1n perspec tive.

The book mark in accordance with this invention is preferably formed Cf celluloid 0r other equivalent pliable but ordinarily relatively inflexible material in orcler that it may be cln1able, 110t subject t0 deterioration, cheap a.ml reatlily cleaned, il soiled. It compriscs an elongatecl main portion 5 having a downvardly extending tongue 6 cut 0ut therei10n1 but joining saicl portion a1; its t0p 7 to fonn the clasp 5, G. F01 convenience, both parts 5 and 6 111a be pointecl as at 8, 9 so that the clasp may be easily inserted within the bincli1ig 0f a book. As shown in Figure 1, the flap 5 is aclapted t0 be inseried between 11l1e back bincli1ig 11 0f the book ancl that portion of ul1e leaves 10 01 the book where they are sewecl together so as t0 stradclle the bindlng ancl grip it therebetwcen.

'1l1e top 01 the clas p is convenicntly. but not necessarily, be1it ove1 110 lie at an angle 01 approxinaafely 90 t0 thelfiongne portion. as at 13, and his inwarclly "ci .1neid ortion 13 is formecl 'Wll'll an elongatecl slot 14.- Thc Slot 14 is prcferably arcuate ancl may C0n veniently have the 1em0te siclc tl'1ereof curvecl as sl10wn ab 15 so as Co f01n1 wha'n is, in eilcct, a D-1ing. Tl1e clasp is thus carriecl 0n the straightsicle 0f the D-ring ancl a place mark, 110W t0 be clescribecl, is carriecl 011 the curvecl side 21 cf the ring.

Tl1e place mark consists of a relativelv still? arm 17 also conveniently i0nned 0f cellnloid er the equivalent, Wh1Cll arm l1as a clownwarclly bent finger 18 at 0ne cxtrcmity ancl is lf0nnc l at the 0ther cn l Wlll) an enlarggc(l p01l1i0n 19 having tl1e hole 20 thcrein. This hole 20 is 0'f a diamel ex snllicienlz t0 reccive tl1e curved .slde 21 of thc 1ing aml have full lreed01h 0T: nxovcn1ent tl1ereonl F01 convenience in assen1bly thc enlarged part 19 is slottecl. as at 22 in onlcr t0 Slip the D-ring into the hole 20. 1

t is obvious that the clasp 5, 6 may slide along the back bincling 11 between the covers 24 ancl 25 ancl thus be arljustable ancl capable 0f use in either a thin book 01 a thick book. as for instance in either a thin text book 0f an orclinary slzecl novel 0r a dictionary or eneyclopeclia. The place mark 17 is furthermore acljustable with respect t0 the clasp so as t0 be capable 01. insertion between any two leaves of the book. The clownwardly extencling fingeris practically movable 0n an a10 clescribed about the vertical axis of the clasp 5, 6 While the D-ring 21 and large hole 20 perrnits a freeclom 0f move1nent which enables the finger to adjust itself parallel t0 Ehe leaves zt any point. As the place n1a1k 1'7*22 is relatively still, the book will naturally fall open, when desiled, at the place Wlll' the place mark is inserted anal there is thus 110 (langer of tearing the leaves when l;he book is openecl as would be the case where u ribbon- 01 cord were usecl 130 mark the place.

Various modifications Wlll 0ccur t0 those skilled in the art in the composition und coi1figuration 0f the component elements going t0 make up the book nmrlz 215 a Wh0le an l 110 limitation is intended by the illustration in tho accompanying clmwings 01 plnraseology in the foregoing specification, except FLH indicated in the z1mqendccl claims.

\Vhat I clai1n is l. A b00k 1nark comprising in combinution, a clasp adnpcecl to grip the back binding of a book ancl formed with an elongated slot and a relatively inflexible plane mark formecl ab one end with means to he rec=eivecl in and slide in ehe sl0t und atthe opposite end with an angularly bent finger f01 insertion between any two leaves 0f' a book.

2. In a book mark, a clasp comprising a flap formed with a downwarclly extencling tongue cut out therefrom, said flap being adapted t0 be insertecl Within the insicle of the back binding 0f a book with the tongue outwardly 0f saicl binding, so as t0 grip the binding the1ebetween anal said clusp being also formecl ab0ve the tongue With an elongated sl0t clefinecl in pa.rt by an arcuate side remote i1om the tongue, und a place mark lormecl witl1 21 hole at one en(l to receive the mcuate sicle 0f the slot and slide With respect thereto, ehe, opposite end 0f the arm bein[g bent at an angle 1"0r insartion bl ween any two leaves 0f a book.
